Ender 3 V2 Y stepper motor cooling mount 40mm fan

I noticed my y stepper motor on long prints would get so hot I would get burned if I touched it.  I made this to fix this issue.  The stepper now is warm, but will not burn me anymore.  

This was printed with Red translucent PETG.  

Recommended settings:

78 - Bed with garolite (70 if you don't have garolite)

245 extruder

70mm/s with klipper or 35 mm/s with marlin

20% infill - I didn't really notice any infill needed on this print since it is so small.
